Abstract: The present invention provides a leveling control system for a forestry machine (10) employing position sensors that relay information about the orientation of the carriage (12) in relation to the swing-house assembly (14) in order to control roll and pitch in a manner that maximizes the operating envelop of the leveling mechanism (38). The angles of pitch and roll of the swing-house assembly (14) in relation to the carriage (12) are measured and/or calculated and a controller (24) limits operation of the leveling mechanism (38) to an operating envelop that may be described in terms of pitch and droll. The cylinders (54, 56) are decelerated gradually as the operating envelop is approached. The controller (24) can include an automatic leveling mode. The controller (24) can change the function of the fore, aft, left and right operator controls so that they are true from the operator's frame of reference regardless of the rotary position of the cab relative to the carriage (12).

Abstract: An improved suspension apparatus and method for damping vibration arising in liquid vortex mixers of the type pivotably supporting a mixing frame assembly and suspending the assembly by at least one spring for mixing a liquid coating using both spin and orbital rotational movements. A pivoting support is located between the mixing frame assembly and a base. A damper in the form of an annular ring is used to damp pivoting movement of the mixing frame assembly. Various pivoting mounts may be used to pivotably support the mixing frame on a base. A bushing provides accommodation of a misaligned spring mounting end turn using a V-groove to retain the spring mounting end turn, and may include an eccentric feature to allow adjustment of the spring mounting length.

Abstract: An improved apparatus and method for balancing paint mixers including pivotably supporting a mixing frame assembly and suspending the assembly by at least one spring for mixing a liquid coating using both spin and orbital rotational movements and adjusting the lowest rotational resonant frequencies of the mixing frame assembly to be substantially below the lower of a pair of forcing function frequencies corresponding to the spin and orbit velocities. Optionally one or more dampers may be used to damp pivoting movement of the mixing frame assembly.

Abstract: Apparatus and method for automatically determining which of at least two forces to apply to a paint container in a mixing apparatus that is capable of clamping various sized paint containers. A clamp motor drives a clamping apparatus toward a paint container and a current rise signals engagement of the clamp with the container, whereupon a selection is made from a predetermined set of forces to apply to the container based on the time of energization and voltage applied to the clamp motor.

Abstract: A process for increasing or reducing the internal pressure of at least one hollow body (HK—1, HK—2, HK—3) to a specified set internal pressure. The set internal pressure is adjusted so that several pressure-increasing steps or pressure-reducing steps are conducted successively until the internal pressure deviates from the set internal pressure at most by a specified tolerance. Each of these steps brings about a pressure increase or pressure reduction the amount of which is not larger than a specified upper limit. In this way, impairments of comfort owing to the rise in pressure or the reduction in pressure are especially avoided. The actual internal pressure is only measured at the beginning of the process. In one design of the invention, this amount depends upon the volumes of the hollow bodies (HK—1, HK—2, HK—3) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.

Abstract: The invention relates to devices (50, 100) and a method for the coating of conductor lines, in particular for the insulation of stator windings of rotating electrical machines. According to the invention, an extruder head (50) is provided for use in a device for the coating of a conductor or a conductor line (72), having at least one extruder die (56), which is connected on one side to a supply conduit (58) for feeding the coating material. On the other side, the extruder die (56) opens out into into a region to which the conductor that is to be coated or the conductor line that is to be coated is adjacent during operation. Furthermore, the outlet of the extruder die (56) can be closed by means of a seal (57).

Abstract: A keyed paint container holder for paint mixers having a pivoting interlock key movable with respect to a paint container receptacle of the holder for orienting a rectangular footprint paint container to have a handle of the paint container in a corner of the holder adjacent the interlock key. The interlock key has first and second portions and is pivotable with respect to the holder to at least first and second positions and, optionally, to a third position. The holder accepts a cylindrical paint container as an alternative to the rectangular footprint paint container.

Abstract: The insulating duct (6) is formed by a material which is built up in layers and is shaped in the manner of an L. The base of the L, which serves as the duct bottom (8), is of rigid design, whereas that limb of the L which serves as the duct wall (11) is of flexible design. A reinforcing insert (12, 13) is placed into the duct bottom (10, 11) and is guided into that part of the duct wall (10, 11) which adjoins the duct bottom (7, 8). In a U-shaped slot-insulating means formed from two of these insulating ducts (6) the radii located at the transitions between the base and the limbs of the U then exhibit great strength. During operation of a rotating, electrical machine into whose rotor a slot-insulating means produced in such a manner has been inserted, migration of the slot-insulating means because of centrifugal forces is very reliably avoided.

Abstract: The invention relates to a method for applying the main insulation of original coil forms, in particular for stator windings, whereby the original coil forms have a rectangular cross-section and the main insulation consists of elastomer.

Abstract: The structural element (1) for transferring mechanical forces between subassemblies at different electric potentials has an electrically insulating body which is provided with a mount (4) at each of it ends. The electrically insulating body at least partially contains LCP material. The mounts (4) are connected non-positively and positively to the electrically insulating body. Thanks to the use of LCP material, the structural element (1) can be made with particularly low mass, at low cost and with high mechanical strength.

Abstract: A supporting insulator has an insulator body in the form of a disk and is made of a cured casting resin, and has at least one cast-in fitting to which high voltage is applied and which is cast in the insulator body and passes therethrough. The cast-in fitting has a cylindrically constructed outer surface which the insulator body encloses. A lip which tapers outwards and is closely connected to the outer surface of the cast-in fitting, is integrally formed on the insulator body. The lip mechanically decouples an edge zone of the insulator body from the actual insulator body.

Abstract: A packaging container comprises a foil laminate comprising at least two layers in which openings are formed. The two layers are joined together over their entire surface area, except for in a striplike channel. A valve strip is disposed in the channel and in valvelike fashion covers the openings of the inner layer. If there is an overpressure in the packaging container resultant gas can escape into the open through the openings and the valve strip acts like an overpressure valve. As a result of the specialized disposition and embodiment of the valve strip and of the openings, a reliable escape of gas produced is achieved.
